摘要: 采用5种化学杀菌剂和2种生物杀菌剂对番茄灰霉病菌进行室内毒力测定,并通过EC50值和病原菌的抗性水平进行抑菌效果对比。结果表明:在5种化学杀菌剂中,乙霉多菌灵与啶酰菌胺抑菌效果最好,EC50值分别为139.64,155.96 μg/mL时番茄灰霉病菌对其表现敏感;在2种生物杀菌剂中,3×108 CFU/g哈茨木霉菌抑菌效果较好,EC50值为139.77 μg/mL。盆栽试验结果也验证了乙霉多菌灵与啶酰菌胺可以较好地防控番茄灰霉病的发生。

Abstract: The indoor virulence of Botrytis cinerea was determined by five kinds of chemical fungicides and two kinds of biological fungicides,and the antibacterial effect was compared by the EC50 value and the resistance level of the pathogenic bacteria.The results showed that among the five chemical fungicides,the antibacterial effect of carbendazim and boscalid was the best.The EC50 values were 139.64 μg/mL and 155.96 μg/mL,respectively,which was sensitive to Botrytis cinerea.Among the two biological fungicides,3×108 CFU/g of Trichoderma harzianum had a better antibacterial effect,and the EC50 value was 139.77 μg/mL.The results of the pot experiment also verified that carbendazim and boscalid can better control the occurrence of tomato gray mold.

Key words: Chemical fungicide, Biological fungicide, Tomato gray mold, Indoor virulence determination
